derived unit

the overall displacement is calculated based on the plane-section assumption, and the local displacement is derived through a unit length of transverse segment in longitudinal direction of the stiffened girder.

主梁中任一点的总位移为整体位移和局部位移之和，按平截面假定计算梁段单元整体位移，沿加劲梁纵向取单位长度横向条带计算单元的局部位移。

Derived unit model structure is clear, and reflects mechanism of system internal relevancy and external correlation.

导出的模型结构清晰, 较好的反映了系统内部关联和外部联系机制.

For AUV and mass-varying AUV in 6 degrees of freedom ( DOF), the dynamic equations of motion with applying generalized vector notation are derived. In these equations, the attitudes are represented by the 4-parameter unit quaternion ( Euler parameters) and Euler angles.

By introducing the concept of the target& existence unit, the method of the rank detection is first applied to the field of signal processing in television tracking and measuring system, and the structure of the detector is derived from statistical theory.

本文通过引入目标存在单元的概念，首次把秩检测方法应用于电视跟踪测量系统的信号处理领域中，而且从统计理论上导出了检测器结构。

the obtained results can't be derived by radiation network unit in the literature and are the same as those by the traditional method.

并用此分析求解一般气体辐射条件下火焰炉的辐射热交换问题，得到了用文献[1]的网络单元不能导出的传统法的结果。
